CacheItemRemovedCallback

CacheItemRemovedCallback

serializable

System.Web.Caching (system.web.dll)

delegate

Functions with the CacheItemRemovedCallback
signature can be used to respond to the
onRemoveCallback when an item is dropped from the
cache. For example, this could allow you to perform related cleanup
tasks. You are provided with the cache object, its key, and the
reason why it was removed (using the
CacheItemRemovedReason enumeration).

To specify that a given method should be used for the
onRemoveCallback, create a
CacheItemRemovedCallback delegate that points to
the method, and pass it as an argument to the Cache.Insert(
) method.
